摘要:

为探究不同土壤调理剂用量对重金属污染耕地的改良效果及对除虫菊种植的影响,本试验采用单因素随机区组设计,分别设置每667 m2施用0、50、100、150、200 kg土壤调理剂(对应CK、T1、T2、T3、T4处理)。结果表明:与CK相比,T3、T4处理显著(p<0.05)降低了土壤容重、总镉含量和有效态镉含量,其中,T4处理效果最优,对应指标分别为1.19 g·cm-3、1.52 mg·kg-1和0.62 mg·kg-1;土壤pH值在T2、T3、T4处理下均显著提高,亦以T4处理最优,达6.28。在除虫菊种植方面,与CK相比,T2、T3、T4处理显著缩短了除虫菊生育期,且以T4处理组效果最优;T4处理的株高和茎粗显著增加,分别为91.67 cm和7.03 mm;除虫菊干花产量和产值在T2、T3、T4处理下显著提高,以T4处理最高,每667 m2分别为184.06 kg和11 043.38元;土壤调理剂并未显著改变除虫菊素含量,但T2、T3、T4处理通过提高除虫菊产量从而显著增加了除虫菊素的总产量。综上,在重金属污染耕地中每667 m2施用200 kg土壤调理剂,有利于土壤改良和除虫菊的种植。

Abstract:

To investigate the effects of different soil conditioner dosages on the remediation of heavy metal-contaminated farmland and its impact on pyrethrum cultivation,this experiment adopted a single-factor randomized block design. Treatments included applying 0,50,100,150,and 200 kg of soil conditioner per 667 m2(corresponding to CK,T1,T2,T3,and T4 treatments,respectively). The results showed that compared with CK,T3 and T4 treatments significantly(p<0.05)reduced soil bulk density,total cadmium content,and available cadmium content,with the T4 treatment showing the best performance,achieving values of 1.19 g·cm-3,1.52 mg·kg-1,and 0.62 mg·kg-1,respectively. Soil pH value was significantly increased in the T2,T3,and T4 treatments,with the T4 treatment again being the most effective,reaching a pH value of 6.28. In terms of pyrethrum cultivation,compared with CK,the T2,T3,and T4 treatments significantly shortened the growth period of pyrethrum,with the T4 treatment performing the best. The plant height and stem diameter in the T4 treatment increased significantly,reaching 91.67 cm and 7.03 mm,respectively. The dry flower yield and output value of pyrethrum were significantly higher in the T2,T3,and T4 treatments,with the T4 treatment achieving the highest values of 184.06 kg and 11 043.38 yuan per 667 m2,respectively. Although soil conditioner did not significantly alter the pyrethrin content,it increased the pyrethrum yield in T2,T3,and T4 treatments,resulting in a significant increase in total pyrethrin yield. In conclusion,applying 200 kg of soil conditioner per 667 m2 in heavy metal-contaminated farmland is beneficial for soil improvement and pyrethrum cultivation.
